 Le brevet luxembourgeois J7 880 a fait connaître l'uti- lisation, comme éléments amortisseurs et simultanément abaorbeure du son d'un faux-plafond, de   cavités   résonnantes dans lesquelles la plaque creuse est constituée d'un matériau   céramique  la cavité   est   remplie,de manière conventionnelle,   au   moyen d'une couche de fibres de verre ou minérales et   est     recouverte ,

On peut soit fabriquer séparément les corps amortisseurs et   les   plaques céramiques puis   les     réunis*   de manière amovible ou les coller par un   adhésif   approprié,   ou   bien on introduit, lors de la confection de la plaque, dans les   @   trous de celle-ci, le matériau du corps amortisseur, par exemple les petits tubes disposés parallèlement les uns aux autres et on réalise la liaison des éléments du corps amortisseur entre eux et avec la plaque,

   à l'aide d'une cuisson à grand   tout   
Les plaques qui, généralement, sont carrées et ont entre 10 et 20 cm de coté, peuvent être apposées de la manière habi- tuelle sur une construction de force portante suffisante (par exemple une ossature),qui fixe la distance entre la plaque et le mur ou le plafond. Cette distance à la paroi qui, comme mentionné est, à coté d'autres grandeurs, d'une importance

 essentielle pour la fréquence de résonnanoe, est comprise entre environ 5 à 3o ara.

Par ces trous l'eau de nettoyage pénétrant dans la cavité peut s'écouler en entraînant: les saletés.

   On doit tenir compte de ces ouvertures lors de la détermination de la   résonnance   du dispositif, 
Dans les endroits où le revêtement est exposé à de fortes souillures, s'indiquent les plaques avec corps amortis- seurs amovibles* Les pores obturés de telle garniture peuvent être dégagea par lavage des un liquide de   nettoyage.

The plates which are generally square and have a side between 10 and 20 cm, can be affixed in the usual way on a construction of sufficient load-bearing strength (for example a framework), which fixes the distance between the plate and the wall or ceiling. This distance from the wall which, as mentioned is, next to other quantities, of importance
 EMI3.2
 essential for the resonance frequency, is between about 5 to 3o ara. The air mattress between the plate and the wall or ceiling can be cut, in a horizontal and vertical direction, by strips of non-porous material (eg masonite), placed at the joints of all two or three places.



   In order to dispense with the placement of the framework in the case of small distances between plate and wall, one can apply by casting, on the perimeter of the plate and perpendicular.

   Small soiling can be removed by ordinary cleaning means, in particular by washing dares sprayed under pressure on the plate * In this case, one or more additional holes are provided in the plate, either on its lower edge, when 'it was agitated (for the lining of walls) of plate with cast edges, or in other suitable places, then opening p. eg, on a trough-shaped cavity formed in the rear face of the plate (for covering ceilings). Through these holes the cleaning water entering the cavity can flow out, entraining: dirt.

   These openings must be taken into account when determining the resonance of the device,
In places where the covering is exposed to strong soiling, the plates with removable shock-absorbing bodies are indicated. The pores blocked by such a lining can be freed by washing out a cleaning liquid. This formula is particularly advantageous when the covering of walls or ceilings is designed for a narrow strip of
 EMI4.4
 frequencies, because then the soiling could act particularly strongly on the resonant frequency and on the damping.

   In the interest of low labor consumption when cleaning such plates, the number of damping elements of each plate should be chosen as low as possible.
